Eric V, Duke of Saxe-Lauenburg

[2] In 1411 Eric V and his brother John IV and their father Eric IV pawned their share in the Vogtei over the Bailiwick of Bederkesa and in the Bederkesa Castle [de] to the Senate of Bremen including all "they have in the jurisdictions in the Frisian Land of Wursten and in Lehe [de], which belongs to the afore-mentioned castle and Vogtei".

[3] Their share in jurisdiction, Vogtei and castle had been acquired from the plague-stricken Knights of Bederkesa,[3] who had dropped into decline after 1349/1350.

Armies of both cities opened a second front and conquered Bergedorf, Riepenburg castle and the Esslingen river toll station (today's Zollenspieker Ferry) within weeks.

However, in 1356 Emperor Charles IV exclusively accepted Saxe-Wittenberg as electorate, with Saxe-Lauenburg not giving up its claim.

However, Sigismund, Holy Roman Emperor, had already granted Margrave Frederick IV the Warlike of Meissen an expectancy on the Saxon electorate, in order to remunerate his military support.
